Hi Radu Yes... Toby told me they are in the stage side. The interface as far as I understand is just a visualization... If you could do it next week that would be wonderful since I don't expect to have things ready until then anyway... I added my email with Toby bellow... Thank you very much... Regards, Hugo I pasted bellow my email and his reply... =========================== EMAILS I dont think this would be particularly easy to do, however if you want to you can create visualisation in stage using the graphics2d interface. Have a look at the examples in the source and docs on the. i believe this will be the easiest method for achieving what you want.

Hi Hugo, Unfortunately, I have no time this week (or I might during the weekend, but I will be away in .nl). Last time I checked there was no data structures defined in player for graphics2d. Are they all on Stage's side? Radu.

Hello... I was wondering when do you think you will add the Graphics2D interface to the javaclient2? Cheers, Hugo |

The position/header control are not completely ported from Javaclient1. I would actually appreciate some help on that since I'm going to be swamped this week and the next one with other things. If not, I will try to fix them when I come back.

Following Fred's advice, Javaclient2 2.0.1 is up at SF.
If any other bugs will be discovered, and/or player 2.0.1 will bring
something new, I'll build Javaclient2 2.0.2.
Changes:
* PULL mode + AddReplaceRule finally works fine. Example on how to use it:
<PlayerClient>.requestDataDeliveryMode
(PlayerConstants.PLAYER_DATAMODE_PULL);
<PlayerClient>.readAll ();
<PlayerClient>.requestAddReplaceRule
(-1, -1, PlayerConstants.PLAYER_MSGTYPE_DATA, -1, 1);
<PlayerClient>.readAll ();
* Changed Position1dInterface to match Brian's refactorization.
* All reads are blocking now (read -> readFully) so at least the client gets THE data (get/setTimeout disabled for now).
* Several bugs fixed, including <Position>.setSpeed (thanks to Hugo Marques), <Sonar>.read (the last value of the sonar values array wasn't being read), and <PlayerClient>.readAll (sometimes in.available () doesn't return anything - delay between Player sending data and the client receiving it => get/setTimeout)
Enjoy,
Radu.

I forgot to mention that... To be consistent with the Player/Stage versions, I will wait until Brian releases a bugfix version of player later this week and then build one for Javaclient too. Until then, CVS is our friend :) Radu. |

Hellos, Some changes (if you haven't followed the P/S users/developers threads recently) have occurred to Javaclient2's way of dealing with data: a) non-threaded mode In a non-threaded mode (default, or when the client sets the <PlayerClient>.setNotThreaded () explicitly), the user must call <PlayerClient>.readAll (); whenever he wants to get new data from the Player server. b) threaded mode In a threaded mode (when the client calls the <PlayerClient>.runThreaded (...); method), the calls are automatically read by the PlayerClient thread, so all the incoming data will be placed automatically in the structures of the respective interfaces. Besides these two basic operating modes (which are Javaclient-specific), the Player server itself has two ways of sending data to the client: PUSH and PULL. Right now the default is PUSH, thus, you can consider that besides the two options (a and b) mentioned above, we have two more: c) non-threaded mode, PULL mode The difference between this mode and a) is that the user must call: <PlayerClient>.requestDataDeliveryMode (PlayerConstants.PLAYER_DATAMODE_PUSH); <PlayerClient>.readAll (); and optionally: <PlayerClient>.requestAddReplaceRule (-1, -1, PlayerConstants.PLAYER_MSGTYPE_DATA, -1, 1); <PlayerClient>.readAll (); The requestAddReplaceRule is important for those cases where you encounter "warning : tried to push onto a full message queue" messages on the Player side. Basically it enables the new mechanism available in Player2 and tries to deal with those situations where the link between the server and the client is slow or the data is produced really fast, and the client gets delayed data. So, an AddReplaceRule with the type PLAYER_MSGTYPE_DATA will replace data with newer versions, ensuring that the client gets data as up to date as possible. d) threaded mode, PULL mode Same as in case c), the client has to issue the requestDataDeliveryMode and requestAddReplaceRule (optionally) explicitly. The difference is that readAll () is not needed here, since the PlayerClient thread will take care of it. So: <PlayerClient>.requestDataDeliveryMode (PlayerConstants.PLAYER_DATAMODE_PUSH); and optionally: <PlayerClient>.requestAddReplaceRule (-1, -1, PlayerConstants.PLAYER_MSGTYPE_DATA, -1, 1); .... suffices. For any other questions don't hesitate to e-mail here on the java-player lists, or directly on playerstage (if the question is not Javaclient2 generic).

Hi Radu... It sounds like a good solution. Unfortunately, I never quite got the = conditions to force the error... however, I would assume that if you = have many programs open (like I had) it would be more likely the error = to apear as player would not have time to reply before the line = "is.available()" in the JavaClient. Indeed I had two agents, a simple = one for tests and a second one which has a graphical interface with = loads of stuff associated with it, and the bug appear much more often in = the second one than in the first one... Hope this helps...

Hi Hugo,
You are *quick*! :) But okay, I got this one covered...
The simulation interface has a data (and a command for that matter)
placeholder indeed, but they are not used. If you want to get/set the
Pose, you need to do something like this:
public static void testSimulation (SimulationInterface simi) {
simi.get2DPose("p0");
if (simi.isPose2DReady ()) {
PlayerSimulationPose2dReq pose =
simi.getSimulationPose2D ();
System.err.println (writePose (pose));
}
PlayerPose pp = new PlayerPose ();
pp.setPx(1);
pp.setPy(1);
pp.setPa(1);
simi.set2DPose("p0", pp);
}
...For example.... (writePose is just a method that parses the values
nicely).
So isDataReady() is useless in this case, since Stage will never send
Simulation data (for now).
If you let me drink my morning coffee, I will commit the changes, and
upload three of the previous Javaclient1.6.5 examples that I modified
last night for 2.x, as well as some general test routines for 13 interfaces.
Radu.

Hi Hugo,
First of all, MANY THANKS for the bug reports!
I managed to fix both bugs, but the CVS at SF doesn't work for me right
now. I will try to commit the changes in the morning.
I also found a bug in the SonarInterface, and fixed that one too.
Cheers,
Radu.

Hi...
I found the reason why it was given the exception. the reason was that =
in the method readAll of PlayerClient when the test is.available was =
being made some times there was nothing. Since I'm really in a hurry I =
made a sort of dirty fix that you might want to have a look:
********************* code
public void readAll () {
if (isThreaded) return;
try {
int i=3D0; // Added by HGM
while(is.available() =3D=3D 0){ // Added by HGM
if (i>10000) break; // Added by HGM
i++; // Added by HGM
} // Added by HGM
while (is.available() !=3D 0){
if (read () =3D=3D PLAYER_MSGTYPE_SYNCH){
break;
}
}
} catch (IOException e) {
throw new PlayerException ("[PlayerClient]: Error reading =
data",e);
}
// while (read () !=3D PLAYER_MSGTYPE_SYNCH);
}
****************************** end code
regards...
Hugo

Hi... I finally managed to receive the laser though I still obtain the error I = sent yesterday quite often... somtimes it starts like this: /************************** Player v.2.0.0 selected devices [localhost:6666]: 6666:position2d:0 (stage) 6666:sonar:0 (stage) 6666:laser:0 (stage) 6666:blobfinder:0 (stage) 6666:fiducial:0 (stage) Connecting too: localhost port: 6666...

Hi...
I tried to track the problem... and I have some more stuff that you =
might want to have a look. I manage to obtain the laser interface using:
CODE *******************************************
robot =3D new PlayerClient (host,port);
System.out.println (" Connecting too: "+host+" port: "+port+"...");
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace(); //To change body of catch statement use File | =
Settings | File Templates.
}
laserInterface =3D robot.requestInterfaceLaser(0, =
PlayerConstants.PLAYER_PLAYER_REQ_DEV);
END CODE =
***************************************************************
Although, this seems unstable since sometimes the laser interface is =
null. When I manage to have the laserInterface!=3Dnull I obtain null =
afterwards when I try to call laserInterface.getData(). And if I try to =
check whether the data is ready (laserInterface.isDataReady()) it never =
is...
I hope this helps... and I also hope that is an easy bug since I really =
need to finish an experiment using Player2/stage2 this weekend...
Thank you very much...
Regards...
Hugo

Hello...
I just installed the javaclient2 in my computer and have a couple of =
questions...
1 - First without the position interface, which interface should I use =
to move the robot now?
2 - Is there a sample agent which uses javaclient2?
3 - I receive an exception when trying to request the laser interface =
(data below)...
Thank you in advance...
Hugo
CODE **********************:
{
...
robot =3D new PlayerClient (host,port);
System.out.println (" Connecting too: "+host+" port: "+port+"...");
LaserInterface =3D robot.requestInterfaceLaser(0,'a');
System.out.println (" Laser... ok");
blobInterface =3D robot.requestInterfaceBlobfinder(0, 'a');
System.out.println (" Blob ... ok");
...
}
THE OUTPUT ******************** :
Player v.2.0.0
Connecting too: localhost port: 6665...
errorrrrrrrr
Laser... ok

Let's see... Simulation and Position(1D,2D,3D) should both work (I tested them against Stage CVS). You can grab it from CVS right now and give it a try. If everything goes according to my plans, I will build an official javaclient2 package on sunday, provided that we will test some of the remaining interfaces "on the way" (since the player drivers are not ready too).

Hellos, First of all, sorry for the cross-post. For those who are interested in programing Player/Stage with Java, I just committed an alpha (well, maybe beta) version of the new Javaclient2. I personally tested a big number of interfaces against Stage CVS, but I would really appreciate any additional tests and bug reports. In a couple of days, I will post the new examples (already available on SF), modified for Javaclient2 & Player/Stage2. If anyone wants to contribute something to the tree (code, documentation, ideas, examples), now would be a good time. I would like to synchronize the release of Javaclient2 with the one for P/S, thus minimizing the impact of changing from 1.x to 2.x for our Java users. Thanks, Radu. -- | Radu Bogdan Rusu | http://rbrusu.com/ | http://www9.cs.tum.edu/people/rusu/ | Intelligent Autonomous Systems | Technische Universitaet Muenchen |

Hey Josh, Yeah, I understand. It is a bit "risky". Well let me know if there's anything that you need for the Javaclient 1.6.5/Player 1.6.5 combo. Good luck with your class. Radu.

Radu, We're hesitant to switch to Player 2.0. This is for an undergraduate robotics class and we're already throwing enough at the students.=20 Adding an untested code base to the situation doesn't seem like a great idea. Specifically, we're the most worried about the documentation. Player 1.6.5 didn't have the greatest documentation, and I don't know how much further behind Player 2.0 and Javaclient 2.0 will be. I'm actually using SWIG at the moment to generate an interface for libgazebo. Going straight into libgazebo lets me run simulations much faster than real time. As a long term goal I want to create a higher level interface that can use libgazebo for faster than real time simulations, or player for controlling real robots.

Btw, I just commited a patched AudioMixerInterface to the CVS. Forgot to
say thanks. :)
